Send marketing@anker.com a message and let them know you haven't had any samples on your Power User page in a while. Check it daily as it could Ave had samples and it's just that others have been quick to claim them.

They are revamping it so you can test across all their brands, but you need to apply for the other sister brands

Hmm, could be an issue on their end for you. Send marketing@anker.com a message then and inform them of what's going on. It's going in the weekend for them so you may or may not hear back from them until Monday@AnkerOfficial may be able to help as well
